The evidence in words
The verdict
For single sprint / max strength, Beta-Alanine earns evidence grade D (trivial effect, high consistency) — the evidence does not support the claim. Wrong energy system
How it might work
Carnosine soaks up hydrogen ions produced during high-intensity effort, delaying the pH drop that causes fatigue in sustained hard bouts. The benefit is specific to efforts roughly 1–4 minutes long.
How to use it
3.2–6.4 g/day, split into smaller doses to limit tingling, for at least 2–4 weeks to load muscle carnosine. Timing within the day is irrelevant; total daily intake and consistency are what count.
Safety & cautions
Safe; the only common effect is transient skin tingling. Splitting doses or using sustained-release forms minimizes it.
Bottom line
Legit for repeated hard efforts of ~1–4 minutes. Take 3.2–6.4 g/day split, load for a few weeks, and ignore the tingle.
How it is used
As the entry records it, from the studies it summarises. Not a recommendation for you — doses that suit a trial population may not suit you.
